Metal handled tool



March 3, 1942. M. J. ZIMMER METAL HANDLED TOOL Filed Jan. 17, 1939 Patented Mar. 3, 1942 METAL HANDLED (r001;

Myron 'J. Zimmer, Chicago, Ill., assignor to The Edward Katzinger Company, Chicago, a

corporation of Illinois Application January 17, 1939, Serial No. 251,401 4 Clai s. (Cl. 16-110) This invention relates to metal handled tools, and in particular tools of this type adapted. for kitchen use.

This invention relates more especially to the manufacture and production of a metal handled kitchen tool or the like embodying a tool and handle stub assembly and a coacting metal shell to form a hollow metal handle portion complementary to said stub assembly.

It is an object of this invention to provide a handle whose construction and assembly is such that the same may be readily manufactured under conditions consistent with the production of relatively inexpensive kitchen tools and yet resulting in the creation of an article comparable in appearance and construction with the more expensive goods of this type.

With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawing'wherein:

Fig. l isa side elevation ofa :metal handled tool constructed in accordance with this invention, with a dotted line representation of a typical tool blade.

Fig. 2 iscan elevational view-of the handle elements, spaced one from the other, preparatory to assembly. I

Fig. 3 is an enlarged fragmentary sectional view of the handle elements in position for final assembly. i

Fig. 4 is an enlarged sectiontaken on line 4+4 of Fig. 1.

Fig. 5 illustrates a modified form of handle stub assembly and coacting shell.

Reference being had more particularly to the drawing, a tool or kitchen utensil which may be of any suitable form, as indicated in dotted lines in Fig. 1, provides a metal tang or shank ID, the rear end of which is adapted to have a drive fit in the bore ll of a suitable handle end or stub l2.

The stub I2 is preferably formed of wood or other similar material, and is designed to give it the form shown in the drawing or any other desired shape. The stub 12 is also provided with a circumferential projection l3 spaced rearwardly from the toolward end of said stub for a purpose which will hereinafter appear.

Driven or otherwise secured over the stub I2 is a metallic shell or elongated ferrule l2 stamped and drawn to give it the form substantially corresponding to the contour of the stub I2, as shown in the drawing. The provision of longitudinal corrugations or flutes IS in the walls of the, shell l2eserve to give the article a surface which aids in the grasping thereof by the hand of the user as well as to improve its appearance, In fitting the shell or ferrule l2a Ove the stub l2, an offset rim 1 3 formed at the mouth of the ferrule I2? is adapted to engage and embrace the projection-l3 of the stub lz. The ferrule I2 is also provided at its forward end wi a op n n is w h, t

entrance to the bore l l. of the stub I 2, through which the shank IU of the tool such as that shown in dotted lines in Fig. 1, may be passed from a metal blank stampedand drawn to give t ahan e sh e om e e tar tbth st 12 and the stub handle assembly or unit. The open front end or mouth of the shell I4 is provided with an outwardly offset rim 15 defining .a lip adapted to embrace the rim [3% of theferrule [2f and the projection l3 of the stub I2 cooperating therewith. Thus, as shown in Fig.3,the Ijim 13 of the ferrule provides ashoulder at its inner limits against which the projection or bead l3 of the stub 12 is adaptedto-be seated, while the s ou e a t e,,- nn limits of them 15 0f th shell l4 forms a seat for the rear limits of the rim I3 of the ferrule and the corresponding surface of the projection [3 of the stub I2, while the free front edge of the rim [5 on the shell l4 terminates beyond the inner limits of said rim I3 of the ferrule and the projection IS on the stub I2. extreme edge of the rim I5 is then bent and curled over the forward or inner limits of the bead or projection l3 of the handle stub and the interposed overlying portion of the ferrule l2, to-wit the rim l3 as shown in Fig. 1, whereby the shell l4, ferrule 12* and stub 12 are .clinched By the use of suitable mechanism, the

forwardly of the rear end of the: shell. The projection I3 of the stub I2 serves as an anvil or abutment to aid in performing this clinching operation, and the tight compression of said rims I3 and I5 against said projection I3 creates a water tight joint therebetween. As shown in Fig. 1, the clinching of the rims I3 and I5 results in the formation of a joint between the elements of the handle which appears as an integral head or part of a one-piece handle. With a, joint between the elements as described, the projection I3 of the stub I2 also serves as a reinforcement which materially strengthens the body of the entire handle. 7

As shown in Fig. 5, a stubhandle assembly consisting of a stub I2 of wood, composition or other similar material corresponding to the stub of" the stub.

I2 of the other views, but omitting a meta1'enclosure corresponding to the ferrule IZ maybe created byjoining the shell I4 directly to the projection I3 of the stub I2 to provide 'a tool with a hollow metal handle portion as contemplated by this invention. This is accomplished by interlocking the bead I5 of the member I4 directly with the circumferential projection I3 on the stub I2 While specific examples of this'invention hav been described, it will be app'arent that various changes may be made in the steps and instrumentalities employed in forming a metal handled tool of the characterset forth, all without departing from the spirit of this' invention as defined in the annexed claims. f

What is claimed is:

1. In a handled tool, the combination with an elongated handle stub of wood in which the shank of a tool may be secured, a circumferential projection formed on and spaced rearwardly from the toolward end of said stub, a metal ferrule coacting with the toolward end'of said stub and having its rear edge offset outwardly from the body of the ferrule to forrn-a seat for the projection on the'stub, independent means forming the butt end of a handle having a closed rear end and an open front end with the edge of the front end thereof "offset outwardly from the body of the shell'to form a seat for the rearjedge of the ferrulefand the corresponding portion of the stub, the free front edg'e of said shell terminating beyondsaid-ofiseton the ferrule and being bent inwardly thereover to rigidly j'oin'said shell, stub and ferrule.

2 In a handled tool, the combination of means forming the butt end of a handle includingan elongated metal shell having an open front end 3[ ma handled tool, the combination of means forming the butt end of a handle including a *metal shellfihaving an open front end, independent 'r'neans'forming the toolward end of a handle including a solid handle stub in which I the shankof a tool may be secured, means for 1 nesting said stub in said shell with a substantial portion of the stub disposed exteriorly of said shell, and its rearward end spaced forwardly of .the rear "end of the shell including outwardly offset portions on said shell and stub; a metal.
